Among the countless components that make up electronic devices, the capacitor is a key element that cannot be excluded. What structure does this small part have, what role does it play, and why is it essential in all electronics? In this article, we’ll clearly explain the basic structure, types, and usage of capacitors.     1. Basic Structure of a Capacitor A capacitor basically consists of two conductor plates (electrodes) with an insulator (dielectric) sandwiched between them. Its main function is to provide capacitance , a space to store electric charge. When voltage is applied to the plates, one stores positive and the other negative charges, accumulating energy . 2. How a Capacitor Works Current does not flow through it, but the capacitor stores and discharges charges in response to voltage changes . Thanks to this characteristic, capacitors are used for voltage stabilization, filtering, and timing control in circuits.   ...

Capacitors are essential components in electronic circuits, and they are broadly classified into polarized capacitors and non-polarized capacitors . These two types differ significantly in structure, principle, and application. Choosing the wrong type can lead to circuit failure or even explosion, so it’s crucial to understand their characteristics. This post explains the principles and uses of polarized and non-polarized capacitors in a clear comparison.     1. Principle and Features of Polarized Capacitors Principle: One electrode functions as the positive terminal, and the other as the negative. Incorrect connection can damage the electrolyte, causing leakage or explosion. Thanks to their electrolyte-based structure, they can achieve high capacitance in a small package. Main types: Electrolytic capacitors, tantalum capacitors Features: High capacitance, compact size, low cost, requires polarity marking (+/-) 2. Principle and Features of Non-...
